Stance XR1 Coilovers are our standard single way adjustable coilover. The XR1 is very similar to our Super Sport line, but due to the constant development of our products, has been improved in many ways. The build and material quality has never been higher. Newly designed pillowball and bushing materials increase longevity and performance. The range and consistency of the XR1 damping forces is also greater than previous Super Sports. The most exciting advancement is our corrosion prevention. Our new dual coating process involves an initial Zinc binding finished with a super hard and ultra thin electrophoretically deposited protective layer. This process has taken our products far above and beyond our competitors in terms of corrosion and rust resistance.

Note: Requires welding to OEM spindles

16 Levels of Adjustment

The Stance damping adjuster knob, or “Clicker”, is designed to offer an easy and convenient way to adjust the damping of your coilover. Our heavy-duty adjuster gives a very positive “click” for each of the 16 levels of adjustment, making it easy to keep track of your personalized settings.

Easy Installation

Our coilovers are tested on each and every application to guarantee a perfect fit for your vehicle. Everything from wheel clearances to ride height adjustment is taken into account during the design process to make sure you experience a hassle free install of your new Stance coilovers.

Monotube Damper

Stance Suspension's monotube dampers offer larger oil capacity and a superior piston diameter compared to a twin-tube design. In our monotube dampers, the oil and charged nitrogen are separated by a free floating piston, which minimizes aeration and fade. These features allow for greater heat dissipation, fade resistance and consistent damping force.

Digressive Damping

Digressive valving produces high damping forces at low shaft velocities & softer damping forces at high shaft velocities. Low speed damping gives better control of the chassis movement & provides quicker feedback to the driver, enhancing overall feel & confidence on the road & track. Digressive high speed valving profile blows off big bumps forces for smooth response, giving optimal chassis balance for maximum grip.

Large Range

Our piston has been developed to deliver a large range yet responsive adjustments. Even with this large adjustment range, each click is even and precise to provide excellent fine tuning ability. Winning races has taught us that compliance is key, even for competition setups. Our know how allowed us to fine tune the valving balance providing you the ability to go from compliant & forgiving to firm & responsive with just a few clicks of the knob.

Inverted Monotube

Originally designed for use in professional motorsports, inverted monotube technology has many advantages over upright monotube dampers. Our 45mm strut shaft offers increased lateral rigidity over competitor’s upright dampers that use 20mm shafts. If the shaft is not stiff enough it can cause the damper to bind under heavy loads and limit the suspension travel – leading to premature wear on the shaft seals & piston bands, causing oil leakage. STANCE inverted monotube dampers offer exceptional ride comfort without sacrificing performance.

Piston Rod

Chromoly steel Stance piston rods have been heat treated, chrome plated and machined to precise tolerances providing consistent reliable performance.

Dust Boot & Bump Stop

Rubber Dust Boots are designed to protect the piston shaft from road contaminants. Rubber Bump Stops are utilized on all STANCE dampers to improve ride comfort and protect the damper from bottoming out.

Durable Coating

XR1 uses Electrodeposition polymer coating engineered specifically for our coilovers. Damper cases go through additional zinc phosphate pre treatment before our special formulated coating to deliver the ultimate corrosion protection. New and improved coating has exceeded 1000+ hrs of salt spray test, making it our most durable coating!

Adjustable Lower Bracket

Offered on strut-type applications, CAD-designed brackets are reinforced to withstand the most rigorous loads for racing. Height can be adjusted separately from the spring without sacrificing damper stroke.

Aluminum Lower Bracket

Offered on multi-link suspension. CAD-designed aluminum brackets are lighter than steel, reducing unsprung weight. Height can be adjusted separately from the spring without sacrificing damper stroke.
